Answer:

These all different sources of energy add to the store of electrical power that is then sent out to different locations via high powered lines. It is the energy from the sun that is harnessed using a range of technologies such as solar heating, solar architecture, photovoltaics, and artificial photosynthesis.

<h3>What is electromagnetic waves?</h3>

Electromagnetic radiation are a group of waves which are are produced by the vibrations of electromagnetic fields. Electromagnetic waves/radiation possess the ability to travel through vacuum (i.e. they do not require a material medium for their propagation) while also carrying radiant energy.

Electromagnetic fields which are the sources of electromagnetic radiation, exist as a result of the combination and interaction of travelling electric and magnetic field forces.

Electromagnetic radiations consists of the following waves: radio waves, infrared waves, visible light, ultraviolet rays, X-rays, and gamma rays.

These waves have differing and unique properties such as wavelength, frequencies, ionizing properties, penetrating ability, sources as well as well as uses. However, they have a common property of velocity- they travel with the speed of light, 3.0 * 10⁸ m/s.

In addition to having the same velocity, all electromagnetic radiation exhibit interference and diffraction.

What is the net force on a 4000 kg car that doubles its speed from 15 m/s to 30 m/s over 10 seconds

kozerog [31]

The net force of the car <u>is 6000 N.</u>

Why?

To calculate the net force of the car during the given time, we first need to calculate its acceleration, and then, use Newton's Second Law equation to calculate the net force.

We can calculate the acceleration of the car during the given tieme using the following equation:

$a=\frac{v-v_{o}}{time}$

Substituting the given information, we have:

$a=\frac{30\frac{m}{s} -15\frac{m}{s} }{10s}=\frac{15\frac{m}{s} }{10s}=1.5\frac{m}{s^{2} }$

Now that we have calculated the acceleration, we can calculate the net force:

$Force=mass*acceleration\\\\Force=4000kg*1.5\frac{m}{s^{2}}=6000\frac{kg.m}{s^{2}}=6000N$

Hence, we have that the net force is equal to 6000N.

Have a nice day!

Un ciclista recorre una pista recta de ida y vuelta, en este recorrido:

Elena-2011 [213]

Answer:

a) falso

b) verdadero

c) falso

d) falso

e) verdadero

Explanation:

A) FALSO: la distancia recorrida es independiente del punto de partida y del punto de llegada

B) VERDADERO: para que el ciclista recorra la pista de ida y vuelta es necesario que su velocidad cambie, por lo tanto la aceleración es diferente de cero.

C) FALSO

D) FALSO: en todo momento hay una distancia recorrida en un tiempo en específico, es decir, una rapidez.

E) VERDADERO: el despazamiento sí depende de la distancia entre el punto de llegada y el punto de salida.

Yosemite Sam was sailing his ship at a speed of 67 m/s when suddenly a storm accelerated his boat at a rate of 5.4 m/s^2 over a

Afina-wow [57]

Answer: vf= 364 m/s

Explanation: Use the formula for acceleration:

a= vf - vi / t

Derive for vf:

vf =( at )+ vi

= 5.4 m/s² ( 55s) + 67 m/s

= 364 m/s
